Functions and Examples

control is sent to Step 10, where the route-to number command sends the call to vector 60, which allows the caller to leave a recorded message. The first step of vector 60 contains an announcement command, which is not skipped, since the treatment step is not the first non-gotostep branched to by a goto step that follows an adjunct routing command whose ASAI link is down [the route-to number step (Step 10) in vector 40 is the first such step]. Similarly, neither the wait-timestep (Step 2) nor the second announcement step (Step 4) is skipped.

Returning to Step 7 in vector 40, let’s assume that there are 50 or fewer calls in queue. In such a case, the goto step fails and, as a result, the announcement step (Step 8) that immediately follows this step is skipped. (Remember, even though this goto step does not immediately follow the adjunct routing step, the former step qualifies as a test case because it is branched to by another goto step that does immediately follow the adjunct routing step.) Thereafter, the goto vector step (Step 9) routes the call again to vector 50, which is designed to queue the call and provide standard call treatment.

The following table summarizes the procedures discussed in this section. In so doing, the table refers back to the vectors presented in the previous screen.

Awaiting the Response to the Call Route Request

After the switch sends a route request to the ASAI adjunct, vector processing continues with the following vector steps.

The step that follows the adjunct routing step in effect determines the maximum length of time the switch will wait for the ASAI adjunct to reply with a call route.
